To all whom it may concern.'

Be it known that I, Bum' A. Pmnsoiv, citizen of the United States,residing at kford, in the county of Winnebago and 5 .State of Illinois,have invented certain new and useful Improvements in Knotters, of whichthe following is a specification.

The invention has reference to devices used in the textile srtsforunitin the ends l0 of thread or yarn, and while it re ates moreparticularly to that class of tyin device which is mounted upon the hando an op erative the invention in some of-its phases w in not imited touse in this manner.

provide a knot-tyin implement which is of an advantageous c aracter froma struc tural 'int of view as well as'fr'omian opera'- tive endpoint,reducing Lthe cost of manu- 20 facture to a minimum'consistent with ahigh deree of eiciency in operation. i fr' orespecic ob'ect of theinvention is to pgvide a knetter aving asmoothly and il f operatinactuating mechanism com- 25 l y arrange and enclosed within a smallcylindrical 4casing rotatabl mounted-in a -supporting frame, the who ebeing capable (of su rt upon the hand of the operative in an stantageous manner permitting oft.

improved construction for the" tying The embodiment of the inventionselected for purposes of illustration includes means whereby theknotterfmay be conveniently 56 mounted u on the hand'of the operative.

Brieiiy,l t e knetter comprises a casing 10 i cylindrical in form androtatably mounted in a generally U-shaped frame 11 carried by a member12. By means of this member, 00 together with a strap (not shown); thedevice is mounted u on the hand of theA operative. A tying bi 113- isrotatably supported by the casing through the medium of a spindle 14journaled transversely thereof and having a caring connection with anelement 15 within the casing, the element 15 bein fixed ith reference tothe frame 11.. 4 On t e exter r of the casing adjacent the tying bill`13 is a thread clamping device l -16 which is also fixed with reference.to thefraine 11 so that in theoscillation of the. casing, thetyinlliill moves with reference to said device. e latter is operativelyassociated with the casin so that in the move- 7 ments of the casing edevice is actuated to clamp"and hold the thread ends during theformation of the knot The means for oscillating the, easingV com rises athumb lever 17 made rigid vwith 't e casing, and l $0 torsion s ringllone end of which is mede fast tot e casing and the other end toelement 15 which is ri id with the frame 11.

The casingv 10 is cy indrical in form and ,l comprises a m'ain or cusection 1.0* having BI a cap portion 10" detac ably-'secured in position in any suitable way. Herein said means comprises albowed springmember 19 formed of Wire end having its opposite ends bent outward] soas to project t ough reg- W istering open ngs in the two overlappinportions of the casing. In the iphei wall of the `casing 'is provided aating 20 in whichis journaled one end of the spindle 14, anddiametrically opposite said bearing and secured within the casing is amember 21 providing a. bearin for the op osite end of the spindle. Seimember a o has a socket 22 formed therein to provide a cam barrel foractuating the tying bill in a man- 00 ner well known inthe art. Saidtying bill -iis"carried by the spindle 14 and projects through anopening 23 in the peripheral wall of the casing.

The frame l1 comprises side members 11'-l and 11b spaced apartsuilicient to receive between them the easing 1.0,wli'ieh is rotatablysupported thereb'ygv and 1s rigidly' secured 4upon the member 12.Preferably the upright portions of the frameare shaped t0formguiding,means for use inipositioni'ng the threads to be united inoperative relation to the tyin bill. Thus the member 11'l is shaped so tat its forward edge extends be-V provide a guidingedge 24 which mergesin 'a 'notch' 25 forming aliook merifiber26v for receiving the threadsto beunited.` A The tying bill 13, which is carried by the spindle 14,com rises a rtion 27 fixed with reference. tot e s in le and carrying apivot, pin 28 upon .w ich is mounted a'shear.- ing and clamping jaw29,'and a stationary Qian-'vV or bill 'spring .369i The lower portionofthje jaw29' is sh'irped to provide a com 30 wingl adapted tocbact witthe cam bar- 'rel"`22 for operxiiioii vthereby in the usual mim'ne'r. `A's'shown in' Figs. to 9 inclusive, the ortioiil Zfiff tli'etyingbill' ismade intengrllwiththe spindle 14.

The stationary element 15 comprises a stem 38 disposed coaxially ofthe'casing endv a .bracketf portion 39 ,substantially ci rcular in formand ri 'dly "securedl to the stem. 4The latter inay e provided for thispurpose with a nnge 40 to which the bracket isfrigidly secured.

'Theupper ends of-tiieimembere 48- nd 49 are 'sha to provde-ffstationaryjaws 56 while-t copper end of 'the memberto is'- shaped to!'plroviclelmovable jaw V57. VIn 'order thatt "e casing tney opcillate' withreference to the clampin device, it is provided in its eripheral walwith a slot 58 (Fig. 6) and to hoid the clamping device stationaryduring the movement o the casing, the circular member 39 of the element15 is provided with an arcuate peripheral flange ;ment by the thumb ofthe hand which carries the knetter. The spring 18 which serves torestore the parts to their normal position is in the form of a torsionsprin surrounding the stem 38, and having one en secured u on a pin 62(Fi 2) rigid with the stem and) its opposite en detachably connectedwith a ton e or linger 63 struck nwardl from the peripheral wall of thecasing at Atiie edge of the cu shaped section 10l thereof. The extent omovement of the casin by the operation of the thumb lever 17 isimited bythe engagement of said lever with the lower end of the frame 11; and tolimit the return movement of the casin by the spring 18, a projection 64is provi ed on the lower peripherv of the casing. This projection is anranged to engage with a stationary stop which is herein 1n thc ,form ofa fiat ring member 65 carried by the hand ho ding member 12. This springmember, it will be seen, serves to cushion the impact of the projection.and thus relieves the knetter of undue shock and stress.

Briefly, the operation of the evice is as follows: 'Ihe two strands oftread to be united are placed, with the aid of the guiding edges 24 and24' of the upright members of the .supportingI frame, in operativerelation to the tying bill..13 and the clampin device16`. Relativemovement is then e fected between the tying bill and the thread clampingdevice through the movement of the casing 10 by means of the thumb ofthe operative engaging the lever 17. In this swinging movement of thecasing,l the spindle 14 is swung with reference to the bracket 15 sothat. the pinion 46, meshing with` the stationary gear segment 47,rotates the spindle and hence the tying bill, the parts hein relativelyroportioned so that the tying bi rotates `sagst/,antially through oneand onehalf revolutions. In such rotation of thetying bill, the loops ofthe 'knot to be formed nre made while the threads are clamped by `theclam in device 16. This clem mg action of t e evice 16 is accompli' .bvthe character.

stationary rative connection between the intermediste member 50 of theclamping device andV the cam member 53 secured to the casing, the camgroove 52 being shaped to produce the clamping action upon the initialmovement of thea casing 10. In the continued rotation of the tyin vbill13, the threads are clamped thereby an bill approaches the end'of itsstroke the loops are stripped therefrom while the ends of the threadsremain clamped so as to tighten the knot. lever 17 by the -operative thespring 18 restores the parts to, their initial osition.

It will be'seen that I have prodhced a knottying implement of a veryadvantageous then severed, and as the tying Upon the release of the.,

The construct-ion is simple and the partsare very compactly' arranged.

Moreover, the actuating mechanism is wholly enclosed and the relativelymovable parts so mounted and arranged with reference to each other as toprovide a smoothly operating mechanism of high efliciency.
